Date and time working wrong on iMac 2019
When turning on my iMac every morning, date and time are wrong-sometimes showing 1:00 Fri 01, sometimes date and time from the day before.
Conecting to the internet updates time and date correctly, but I'm worried if there's a hardware issue as the computer does not remember the real time and date after some hours switched off. I've tried a lot of possible solutions- changing location, deleting Localtime file on etc folder, calling Apple customer help...but nothing really works.
Any help or suggestion will be very appreciated!
